Latest Forecast Rain Expected to Raise Levels Again

 

Water levels that were already high from rain on Sunday and Monday are expected to increase again if rain forecast for Thursday and Friday falls on the Rideau River watershed.  

About 12 millimetres (mm) of rain fell overnight and as much as 40 mm more is expected. This could cause flows in the Rideau below Mooneys Bay to increase to about 320 cubic metres per second. While not an issue in the lower sections of the system, such flows typically mean flooding of low-lying areas on the Long Reach, the section of the river between Manotick and Burritts Rapids, with the access roads to the river side communities at risk.

High flows on the Tay River in Perth continue with most of the flow directed through the Little Tay which has caused flooding in Stewart Park. The construction site at Haggart Island Dam is being monitored closely.

The forecast rain can be expected to cause increased flows in the smaller streams such as Steven Creek. Residents in North Gower can once again expect to see the banks close to full through to next week.

Residents are advised to stay away from rivers as the forecasted weather may rapidly increase river flows, and cause slippery river banks.  Parents are encouraged to explain these dangers to their children.
